It was summer, so we could easily sleep on top of the mattress with only light blankets, it allowed me to maintain close contact and skin to skin with her, which helped both of us with bonding.
She never had to cry to let me know she needed a feed or change, because I could react as her body began shifting in discomfort or need, she could latch with much assistance from quite early on so it meant I never had to fully wake for a feed, plus she could comfort suck if she needed to.
It definitely enabled breastfeeding which was good in the early days when it is so easy to be disheartened and quit.
I actually liked it, it felt like a special time when we were up together at night feeding, this is when I felt most motherly and since I had trouble with the first I believe that it enabled this bonding.
It just came naturally to us, she quit it herself at about six months, although we still shared occasionally after that if I had trouble settling her. And it was good for me at the time as I had mobility issues, so being in the same place as each other meant less pain for me.
